Application filed October 12, 1920. Serial No. 416,475.

To all whom it ma concern:

e itknown t at I, EDWARD DONALD CAMPBELL, a subject of the King ofGreat Appliances, of which the following is the specification.

My invention relates to improvements in barbers appliances and the object of the invention is to devise an electrically driven instrument that will actuate hairwcutting clippers in any position. A further object is to provide means for connecting a vibrator to such instrument, and a still further object is to devise means for connecting a drying fan thereto.

My invention consists of the parts constructed and arranged, all as hereinafter more particularly described and illustrated in the accompanying drawing in which:

Fig. 1 represents an elevational view partly in section showing my instrument and the means for operating the clipper mechanism.

Fig. 2 is an elevational view of the removable casing shown in section in Fig. 1.

Fig. 3 is a horizontal section through the same.

' Fig. 4 is an elevational detail showing the bayonet joint locking device for detachably securing the casing to the electric motor.

Fig. 5 is a vertical section showing the removable casing having the drying fan connected thereto. v

Fig. 6 is a vertical section showing the vibrator attachment connected to the removable casing.

Fig. 7 is a plan view showing the clipping attachment, the casing being in section.

Fig. 8 is an enlarged vertical section through the casing showing the clipper attachment. applied thereto.

Fig. 9 is a detail in plan of the upper movable knife (if the clippers.

Fig. 10 is 'a similar detail of the lower fixedknife of the clippers.

Fig. 11 is a sectional detail through the knife operating means.

Fig. 12 is a plan view thereof, and

Fig. 13 is an enlarged vertical section of the vibrator attachment shown in Fig. (5.

Like characters of reference indicate corresponding parts in the different views.

1 is the electric motor provided with a suitable handle 2. 3 is a depending portion through which the shaft 4 of the motor eX- tends. 5 are stud bolts on the side of the depending portion 3. 6 is a Wedge-shaped male connecting member on the lower end of the motor shaft 4. 7 is a. detachable casing having the bottom 8 and the aperture 9 in the side face thereof. 10 are vertical slots extendingdown from the upper edge of such casing andconnecting with the horizontal slots 11, said stud bolts 5 adapted to be inserted into the vertical slots upon the attachment of the casing to the. depending portion 3 and such casing turned when the bolts are at the bottom of the slot 10 so as to bring them into the horizontalslots 11, thus securing the casing to the depending portion 3 of the motor. 12 is a horizontal partition extending across: the casing 7 and provided with depending legs 13 adapted to abut the. interior of the casing and secured thereto by the screws 14. 15 is a vertical stub shaft extending through the partition 12 and mounted in a suitable bearing 16 therein, the upper end being provided with a tapered female connecting {)nember adapted to receive the male mem- '18 is a crank wheel secured to the lower end of the shaft 15 by the key 19 and carrying the .crank pin 20 which pivotally con-- nects the clipper driving link 21 to the crank wheel for the purpose. which will hereinafter appear.

The. above casing has been described as adapted for use with the clipper mechanism. \Vhen it is desired to use it with the drier fanv it is constructed without any bottom 8, and the vertical shaft 15 is of greater length. In this instance a fan casing 22 is provided having the nozzle 23 and the air inlet holes 2-1. 25 is a fan connected to the stub shaft '15.

\Vhen the casing. is used in connection with the vibrator the bottom 8 of such casing has a depending cylindrical member 26 formed thereon, said cylindrical member be ing open to the casing. The stub shaft 15 is in this instance provided with an eccentric foot 27. 28 is a rod extending vertically through the member 26 and having the enlarged hollow boss 29 formed at the top thereof into which the foot 27 on the shaft 15 extends.

The lower end 30 of the rod 28 is enlarged and has a cross aperture 31 extendit is merely necessary to replace the reing therethrough, through which a lateral pin 32 extends, the diameter of the pm 32 being less than the diameter of the orifice ll. 33 is the vibrator sphere having a screw 3 threaded into the bottom of the lower e1 ds 30 of the rod 28. 35 is a cap threaded olito the lower end of the member 26, said c: being provided with a central orifice 30 through which the lower portion of the end 30 extends.

I will now describe my clipper mechanism. 37 is a plate attached to the bottom 8 of the casing 7 by the screw bolts 38, said plate having a depressed foot 39. 40 is a lower knife of the clipper secured to the foot 89 of the plate 37 by the screws 41 which extend through holes 42 in such knife. 43 is a central indenture in the upper face of the knife 40 permitting the head 44 of the 'vertical bolt 45 to be inserted therein. 46

are a plurality of cross channels or slots in the upper face of the lower knife 40.

47 is the upper knife having the notch 48 at the centre of its rear face. 49 is the clipper operating arm having the hollow boss 50 through which the bolt 45 extends. 51 is a downwardly turned foot on the arm 49 adapted to. be inserted into the notch 48 in the upper knife '47, the link 21 being pivotally connected to the upwardly turned portion 52 of such arm 49. is a cover plate extending over the operating mechanism, said bolt 45 extending therethrough and being provided with the securingnut 54 adapted to bear against such plate. The plate is provided with a downwardly turned end 55 adapted to engage the upper knife 47.

The operation of the clipper mechanism is as follows:

By connecting the removable casing 7 to the depending portion 3 by means of the bayonet joints the wedge-shaped male member 6 is inserted intothe member 17 and thus forms a driving connection thereto. \Vhen the motor is turned on, the crank wheel 18 is revolvedv and the link 21 recipwcated. lVhen this occurs the arm 49 is oscillated and as the foot 51 thereof is connected with the removable knife 47, such knife is moved back and forth across the face of the fixed 1 knife 40, thus moving the teeth 56 of the 'knife 47 across the teeth 57 of the knife 40 and effecting the clipping operation.

hen it is desired to use the drymg fan movable casing attached to the clipper mechanism. by the removable casing attached to the fan casing, or where it is de sired to use the vibrator it is only necessary to apply its casing to the motor.

The operation of the vibrator is as follows:

The eccentric foot 27 operating in the socket 29 rocks the rod 28 back and forth about the lower end 30 thereof, thus vibrating the sphere 33.

From the above description it will be seen that the barber in using the instru-' ment will be able to change the attachments with the greatest possible facility, simply by removing the particular casing 7 from the depending portion 3 by disconnecting the same at the bayonet joints. He' can then use any other attachment he requires, and consequently only one electric motor will be necessary to operate the three attachments instead of having to make use of a separate motor for each.
